Solving the expression
we get value of x: 
Step-by-step explanation:
We need to solve the equation
and find value of x
Solving:
![-[-2(x-4) - |1-3|] = -2x18](https://tex.z-dn.net/?f=-%5B-2%28x-4%29%20-%20%7C1-3%7C%5D%20%3D%20-2x18)
Multiply -2 with terms inside the bracket
![-[-2x+8 - |1-3|] = -2x18](https://tex.z-dn.net/?f=-%5B-2x%2B8%20-%20%7C1-3%7C%5D%20%3D%20-2x18)
Solving |1-3| we get |-2|=2
![-[-2x+8 - 2] = -2x18](https://tex.z-dn.net/?f=-%5B-2x%2B8%20-%202%5D%20%3D%20-2x18)
![-[-2x+6] = -2x18](https://tex.z-dn.net/?f=-%5B-2x%2B6%5D%20%3D%20-2x18)
Multiply (-) sign with terms inside the bracket

Multiply 2x with 18

Add 36x on both sdides


Add 6 on both sides:

Divide both sides by 38

Simplifying:

So, Solving the expression
we get value of x:

Answer:</h2>
- option (c) = -19 + x = -21
<h2>Step by step explanation:</h2>
<u>Question</u> : A number added to -19 is -21
<h3>
<u>Solution</u> ↓</h3>
First of all to make equation
Equation means LHS = RHS
For eg we take :-
50 - 20 = 10 + 20
30 = 30
Therefore, LHS = RHS
<h3>
According to the question :</h3>
- Which number would we add in -19 to get -21 and we get LHS = RHS
Make an equation
-19 + x = -21
x = -21 + 19
x = -2
Add -2 in the variable of x
Variable means any unknown value we used in maths. For eg :- x,y,z,a,b,c,p,q,r etc.
-19 + (-2) = -21
-19 - 2 = -21
-21 = -21
Therefore, LHS = RHS.
